  • It used to be that everything in Linux was a file, ideally a text file, so if you could find the right file you could access or change what you wanted. Systemd is a big program that manages a bunch of stuff and creates unique commands within its programs for doing so, which moves away from that principle and turns system management into what feels a bit more microsofty (like the registry editor program vs editing config files, etc) and a lot of people don’t like that. But to its credit, it does solve a few problems with cobbling together a modern system that doesn’t suck.

    That photo is from a film about neanderthals. The phrase “unga bunga” has its earliest known usage in a Bugs Bunny short mocking Aborigines, but it’s a generic enough phrase that I’m not sure you can write off the entire phrase as racist against Aborigines: any nonsense word could be used in its place and I’m not sure anyone creating or sharing the meme has actually watched that Bugs Bunny clip from 1950. It’s just a nonsense phrase used to indicate low intelligence or nonsense. Given that the photo is of a neanderthal, I think anyone seeing the meme will understand that it’s supposed to mean “a caveman would be confused by this” and not about any particular group of modern or indigenous humans. Most usages of the meme imply that the poster themselves is the confused one, so I don’t think a racist would find it very funny to post something like that.

    Given that the words “unga” and “bunga” have existed in print since at least 1700 AD, I’m not sure we can point to that one Bugs cartoon as the definitive and only definition of that particular nonsense phrase. https://books.google.com/ngrams/graph?content=unga%2C+bunga&year_start=1500&year_end=2019&corpus=en-2019&smoothing=3









  • If you can’t feel your hand heating up if you hold it near the oven and sensors or thermometer strips don’t register any temperature increase outside the oven when it’s on then nothing substantial is escaping. The amount of 2.4ghz energy required for indoor communication is on the order of tenths or hundredths of a watt, whereas the amount of energy required to cook food is on the order of 1000 watts. So you’re talking about a 10,000-100,000-fold difference in magnitude.

    For non-ionizing EM radiation like radio waves and normal light (as opposed to ionizing radiation that can cause cancer by knocking bits off your DNA like UV rays and X rays) the danger is in, essentially, cooking your flesh. For radio professionals determining if a microwave antenna or cell phone is safe for your body, we calculate watts per square centimeter, in other words how much electrical energy is delivered to your skin’s surface. When a radio professional messes up and gets exposed to dangerous levels of energy, they experience it as feeling very warm or burning, and may suffer symptoms similar to a sunburn or, worst case, like putting a body part in a microwave oven.

    Also because of how rays of energy work mathematically against surfaces, every foot you stand away will exponentially decrease the amount of energy you’d possibly receive: standing 6 feet away will give you 2.8% the dose versus standing 1 foot away. So even if you have a dangerously defective oven, just don’t hang out with your face pressed to the glass and you’ll have much bigger things to worry about in life.

    TLDR: there’s no voodoo scariness behind microwaves, just try to make sure they’re not warming you up and cooking you, especially for extended periods of time. You’d probably notice if they were.

    The main hazard of putting an electronic device in a microwave is that it heats up and catches fire or ruins your food.






  • A few gigs of zeroes will prevent random drive-bys. At that point the partition and filesystem table of at least the first partition is overwritten and you “can” recover files off it but you’ll be missing filenames and at least half the files will be corrupt due to fragmentation losing track of which files are where.

    I agree with Ono that shred is a good tool for this. If you don’t want to use that, try increasing the block size to at least 1M if not 16M to reduce the overhead.


  • Excellent example of why giant instances are bad ideas. Nazis love forcing you into a “throw the baby out with the bathwater” type choice because it means they can continue their hateful, destructive, genocidal behaviors without consequences. They’re usually not stupid, they know what they’re doing is wrong, they just want to keep getting away with it. So they’ll go nuclear on anyone and everyone in order to maintain their comfy corner of hate.

    Any moderator (or stadium owner) who doesn’t give Nazis jerking off in a corner a lifetime ban is negligent, as you said.
